Hi there, We’ve developed multiple marketplace apps with secure chat, payment systems, and advanced features like geo-localization and multi-currency support. One of our recent projects, called Concio, is a marketplace for experts and learners where experts can create paid events and offer free introductory calls. We integrated Stripe for payments and built a robust chat system using WebSockets. We also understand the importance of logistics in marketplace apps. For Concio, we integrated a third-party calendar API to automate scheduling and reminders, ensuring a seamless experience for both experts and learners. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best, Adil
